BUCKLE.

Application filed September 18, 1922. Serial No. 588,822.

To all whom it may concern:

Be it known that I, SHERMAN D. CLARK, a citizen of the United States, and resident of Seattle, in the county of King, State of \Vashington, have inventedcertain new and useful Improvements in Buckles, of which the following is a specification.

My invention consists of a slide buckle of a type which is especially adapted for use on suspenders, garters and like places where it is mounted upon and used in connection with a web and it may be desirable to shift it along the web.

The object of my invention is to provide a buckle which is well adapted for such uses, which will securely hold the web yet lie fiat and not be too thick and which may be conveniently adjusted along the web.

The features of my invention which I bepatent, will be hereinafter described and then particularly pointed out in the claims which terminate this specification.

In the accompanying drawings I have shown my invention in the type of construct-ion which I now prefer to use.

Figure 1 is an edge view of a buckle showing the manner of securing the web thereto and securing the buckle in adjusted position upon the web.

Figure 2 is a top View of the buckle showing one end portion of the plate or base'in section.

Figure 3, is an end view showing the end portion of the base plate in section and one of the securing loops raised in position to release the web.

Figure 4 is an edge view of the buckle and web secured thereto illustrating another manner of securing the end of the web to the buckle. r

A buckle constructed in accordance with my invention has a base plate 1 whichis made of thin sheet metal having its ends bent over upon themselves so as to form pivot-containing spaces at two opposite sides, in which is pivoted two securing loops 2, preferably each formed of a wire bent into the peculiar sha-pe shown, the ends of such wire being held in the folds of the plate thusformed.

Each of the web clamping or holding loops has its two ends bent to form a U- shaped loop 20. The side of the loop which is formed by the end of the wire lies in lieve to be new and upon which I desire a the space betweenthe central body 1 and ends 10 of the base plate. The other or outer side of the loop extends to a point preferably just short of the'middle of the length of the base plate. The central portion of the wire of which these loops are formed is bent into such a shape that it forms a spring which resiliently presses the loops 20 against the end edges of the base plate.

In the construction shown this central portion of the wire is bent backward upon itself to form two loops 21 and 22 at each side of its center. The outward loops 22 extend from the center outwardly and with the common connecting section 28, form a lever arm by which theclamping members of the buckles may be operated. In the edge of each of the pivot holding loops formed by thebent end of the base plate 1, is formed a slight depression or. notch 12 positioned at the central portion of the bend, into which the curved section of the loop 20 of the clamping member rests when the same is drawn down into the general plane of the base section 1. Each of the ends 10 a similarnotch 11, adapted to receive the same portion of the bend 20when the clamp ing member is drawn up into a position substantially at right angles with the genof a suspender,.is passed through the space between the sections 24: of the wire which are outside of and parallel with the base.

-The said web is passed through this space of each of the adjusting and clamping members 2. It is then looped-back upon itself and again passed through the same space beneath the previous portion of the web, its end then being secured to the body thereof so as to form a loop. This may be secured in any convenient manner as by stitching. In fact the end of the web may be secured to the base section 1 in any desired and feasible manner.

is alsoprovided-at each end of the base with In Figure at a different manner of securing the web thereto is shown. In this figure a loop A of wire is shown as having its ends secured between the central body of the base and overturned ends 10. The end of the web is passed between the outer bar of this loop and the central section 1 and doubled back upon itself, after the manner shown in Figure 4. To this end of the web is secured a narrow metal binding plate 40. When this is done and it is secured in the position shown in Figure l, no other means oi securing it need be employed.

To insure that the end of the web when secured will entirely cover the metal of the base 1, I contemplate providing the end edges of the base 1 with notches similar to the notches 11 and 12, which notches will receive the bend of the loop 4C, thus holding in the position shown in Figure 4;.

The resiliency of the clamping sections 2 serve to hold them seated in either of the notches 11 or 12.

If the clamping sections be thrown up into the vertical position as shown in Figure 3, the web of the Suspender may read ily be slipped between the same and the base section; WVhen the buckle has been adjusted to the proper position, throwing these clamping sections down where they lie in the general plane of the base section, or to theposition shown in Figure 1, causes them to clamp the web between the section 24: and the edge of the base section with sufficient force to prevent the buckle from slipping. In this position the wire loop 2 is seated in the notch 12 at the bottom of the loop 10 of the base plate while the'pivotsections of the wire are held a slight distance inward from the bottom of the loop, as shown in Figures 1, 2, and at. This relation of the parts prevents swinging up the clamping sections except by the use of some force. While held in this position the web is given an offset bend which provides considerable resistance to sliding of the web through the buckle, this being capable of being made sufiicient to hold the web against movement under normal stresses thereon. If it be desired to adjust the buckle, it is very easy to take the two clamping sections between a thumb and finger while pressing the central section down with another finger, thus swinging up and outward the clamping sections and releasing the web. When the loops 2 are thrown into such position at right angles to the base, as in Figure 3, the lead of the web is straight through the loops 2) and the resistance is therefore slight. In this position it may be easily adjusted. The buckle as shown and described is flat, of no great thickness and is protected from engagement with the body at all times by the web.

WVhat I claim as my invention is 1. A slide buckle comprising a base plate having pivot-retaining loops at two opposite edges, web holding loops having one of their sides pivoted in the loops of the base and of a width to permit free sliding of the webs through them when placed at right angles to the base, said web holding loops being resilient and being adapted when swung into a common plane therewith to grip the base to hold the two in parallel position to thereby cause offset bends in the web, which produce frictional resistance against sliding of the web.

2. A slide buckle comprising a base formed of a metal plate having two op posite edges bent over upon themselves and two spring loops pivoting between the bends thus formed, the edges of the plate being notched to provide seats for said loops at the apex of their, saidl bends and at one side at a point to receive the loops when swung into a position at right angles to the plane of the base.

3. A slide buckle comprising a. base having pivot-receiving eyes extending along two opposite edges, and spring loops pivotally mounted in said eyes, said loops being adapted to yield in the direction of the axis of said pivots, and having web holding bars extending parallel with their pivots and spaced from the plate to receive the web between said bars and the base, said base having notches in its edges receiving the loop ends when the loops lie in the general plane of the base and also when swung at right angles thereto.

4. A slide buckle comprising a base and loops pivoted at two vopposite edges thereof to swing over the edge and into a position substantially at right angles with the plane of the base, said loops being adapted to. accommodate the web between them and the base and being bent intermediate of their ends to permit resilientmovement in the direction of their pivot axis, the base having notches in its edge to yielding hold the loop in adjusted position in line with the plane of the base and at right angles thereto.

5. A slide buckle comprising a base and loops pivoted at two opposite edges thereof to swing over the edge and into a position substantially at right angles with the plan of the base, said loops being adapted to accommodate the web between them and the base and being bent intermediate of their ends to provide resilient sections which cause the opposite ends of said loops to resiliently grip the end edges of the base, geld end edges having recessed seats there- Signed at Seattle, Washington, this 11th day of September 1922.
